Abstract

A three- dimensional molecular-dynamics model of Pt3Al with L12 order was developed and found to support the excitation of discrete breathers (DBs) and energy localization on the Al sublat-tice. For an initial lattice temperature of 0 K, large-amplitude DBs polarized along [100] are found to be very weakly damped, retaining most of their initial energy for more than 1000 cycles, while DBs polarized along [111] damped out over ~15 cycles. Because the DBs and their dissipation channels are confined to the Al sublattice, long-lived states with large energy differences between the Al and Pt sublattices occur.
